Economics Standards (from Voluntary National Content Standards in Economics)

Standard 12:  Interest rates, adjusted for inflation, rise and fall to balance the amount saved with the amount borrowed, thus affecting the allocation of scarce resources between present and future uses.

Standard 18:  A nation’s overall levels of income, employment, and prices are determined by the interaction of spending and production decisions made by all households, firms, government agencies, and others in the economy.

Standard 20:  Federal government budgetary policy and the Federal Reserve System’s monetary policy influence the overall levels of employment, output, and prices.


  • Commercial banks provide financial intermediation – i.e. by accepting deposits and making loans they bring borrowers and lenders together; and they “create” money through the expansion of checkable deposits – i.e. by expanding checkable deposits, they expand the money supply.
  • If banks expand the money supply more quickly (slowly) than real output expands, then inflation (deflation) is often the result.
  • In the process of pursuing a profit-maximizing strategy, banks typically keep only a fraction of their deposits on reserve, hence the expression “fractional reserve banking.”
  • Historically, bank balance sheets were subject to “runs” by depositors.  Because these runs tended to spillover to other banks and thus other sectors of the economy, commercial banks have been a target for regulatory oversight
  • There were major panics in the United States in 1833, 1837, 1839, 1857, 1873, 1893, 1907, and 1930-1933.
  • Bank regulation is typically designed to insure “soundness,” including auditing of bank balance sheets, which for nationally chartered banks is done by the Comptroller of the Currency, and the establishment and maintenance of required reserves, which is overseen by the Federal Reserve System.
